concern: Beit known that I, CHARLES Fou'rn, a

d duce a device of this citizen of the U Boston, in the county of Suo'lk and tate of Massachusetts, have invented certain new and useful Improvements 'in -Mixers or Beaters, of which the f specification, reference being had therein r#to the accompanying drawing.

This invention relates to mixers or beaters designed more particularly for beating eggs,

and embodying usually a supporting frame on which are mounted rotary agitators or beaters driven by a rotary masterwheel.

The objects of the invention are to procharacter which will be simple. and durable in construction, inexpensive to produce, effective m operation, and in vwhich there will be little or .no

liability of the operative parts being' clogged by the accumulation of dirt or grease. .A y

With these nds in view the invention consists more. particularly of an improved form of gearing for driving the beater arms, said gearing comprising wheel formed with driving holes therethrough, and driven pinions arranged on opositev sides of thewheel, and provided with teeth adapted to engage through the holes, the said pinions being operatively connected with the beater arms, so that by the,I rotation of the master wheel, a rotary mot-ion will be imparted to the pinions which will impart a corresponding movement to, the beater arms. v

' The invention consists also in an improved form of frame for supporting the operative parts, more particularly the beater arms, to give them firm and extended support.

The invention consists also in an improved form of 'beater arm; and further, in the details of construction and combination of parts hereinafter described and claimed.

In the accompanying drawings: Figure 1 is a side elevation of my improved device; Fig. 2.is an edge view of the same looking in the direction of the arrow in Fig. 1; Fig. 3 is a horizontal transverse section on the line A, A, of Fig. 1, looking in a downward direction. v

Referring to the drawing: the support ing frame of the beater consists of a bracket 1, having a handle 2 xed to its upper end, and an extension 3 fixed to its lower end,

said extension being'in the form of' two parallel rodea fixed at their upper ends to the lower end of the bracket andhaving fixed t0 their lower ends a horizontal plate 5. Fixed to the plate wardly therefrom, is a looped extension 6, the purpose of which is to support the device when it `is in -operation as to prevent the ends of the beaterarms from coming in contact with the bottom of the vessel.' v

The lower end of the bracket portion ofthe frame is provided with vertical bearing openings 7 7, arranged in alinement with correspondmgbearing openings l8, 8a, inthe plate 5, in which bearing openings are mounted 5 and extendingI downin a vesselso two parallel shafts V9 and 10, having con- .I

nected rigidly with their lower ends, beater arms 11 and 12, each of U-form, arranged with their open ends downward. On the upper ends of he shafts 9 and10 and above the bearings 7 and 7a ions 13 and 14, provided. with teeth -15 in the form of conical pointed pins, which are adapted to enga e through openings 16 yin a vertical master riving wheel 17 journaled to thebracket portion ofy the frame, as at 18, and extending at its lower portion between the two pinions, the axes of the latter being so disposed4 relatively to each other and to the wheel that the teeth of the respective pinions will engage simultaneously in different holes of the wheel, as shown in Fig. 8. The master wheel has aliixed to it an operating crank 19 for imparting to the wheel a rotary motion.

As a result of the construction described, it will be observed `that when the master wheel is rotated, the holes therein will en# gage aro willcause said pinions to rotate in opposite directions, thereby imparting a corresponding motion tothe open ended beater arms. By reason. of this form of the driving gearing, there will be no danger of the parts becoming clogged by the accumulation of dirt or grease, the engagement of the teeth through the holes on the master wheel acting to automatically keep said holes open and preventing will be observed that the shafts which carry the beater arms are mounted each in two bearings widely separated from each other, so that the shafts are rmly sustained and their uniform rotaare fixed driven pin` nd the teeth on the pinions andthe accumulation therein of `dirt. Further it tion and parallelism preserved. It will also y be seen that the axes of the lbeaterAarms, 4driven lpinions arranged on opposite sides represented by the shafts 9 and 10, are arof the wheel and provlded with teeth adaptranged respectivelyeon opposite sidesof the ed to engage in said holes, and beater arms plane of the looped. frame 6, the limbs of 'operated by said pinions whereby the teeth thebeater arms- 1n their rotation passing will-serve to prevent .the lodgment of dirt v through the frame, andby coperating with inthe holes.
